Answer:
Explanation:
The biological or chemical change in the quality of water due to the presence of contaminants in water is called water pollution. Most of this contamination as on date is due to various human activities. In fact, humans are responsible for the mass deaths of whales and other aquatic organisms often swept ashore at different beaches in the world. There is an urgent need to look into the measures to control water pollution although a lot many efforts and schemes have already been announced by the Government in this regard. To make the students aware of this we have prepared short and long essays for students which shall inform them about water pollution and the means to minimise it.
Answer: False, it is transported as bicarbonate
Explanation: Carbonic anhydrase is an enzyme belonging to the family of metalloenzymes that catalyzes the conversion of carbon dioxide and water to ions and carbonic acid. This enzyme is found in red blood cells where carbon dioxide enters by diffusion. Once it diffuses through it is then converted by carbonic anhydrase to bicarbonate and hydrogen ions.
That is how its transported in bloodstream, passes through the heart via the venous system, to the lungs. Therefore the answer is False.
